p.s if your getting 60fps with QuickSync, you have a slow process in chain (i.e a filter) with it. Even on my older 4770K I get around 180fps with current version. Older 0.10.5 is 10~15% quicker (but that will be fixed in the future)

For reference, a 1060 is a little over 500fps with 1080p content again although I'm not a real fan of it's output.

You have to be careful comparing speed between versions. The defaults today are very different than previous releases. Mostly tuned towards quality / filesize, thus slower)
